sql_regcase

sql_regcase -- make regular expression for case insensitive match

Description

string sql_regcase(string string);

Returns a valid regular expression which will match string, ignoring case. This expression is string with each character converted to a bracket expression; this bracket expression contains that character's uppercase and lowercase form if applicable, otherwise it contains the original character twice.

Example 1. sql_regcase() example

echo sql_regcase( "Foo bar" );
prints

[Ff][Oo][Oo][  ][Bb][Aa][Rr]
.

This can be used to achieve case insensitive pattern matching in products which support only case sensitive regular expressions.
